Original application filed November 22, 1912, Serial No. 732.971.

Specification of Letters Patent.

To all whom it may concern Be it known that I, JAMES CAV'ANAGH, a

- citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Methods of Making Shoes, of

which the following description, in connection with the accompanying drawings, is a. specification, like reference characters on the drawings indicating like parts in the several figures. I

This invention relates to methods of making shoes, and in particular to a method for use in lasting and fastening shoe uppers to welt shoe inner-soles or to turn shoe soles.

In lasting welt, or turn, shoes by hand or on machines of the hand. method type an example of which is disclosed in United States Letters Patent No. 584,744, dated June 15,1897, the upper is stretched over the last by pincers progressively, or one section after another. and the successively stretched portions of its margin are placed against the lip or rib of the innersole or sole and secured thereto by lasting tacks. These tacks, whether driven by hand or 1nacbinery, lie substantially perpendicular to the plane of the shoe bottom, and are usually driven fairly close together so as to hold the upper securely in position about the last. hen allowed to remain during the subsequent operation of permanently uniting the upper and weltto the innersole by the stitches of the inseaming machine these tacks offer an obstruction to the movements of the needle and awl which frequently encounter the tacks and are bent or broken. In order to obviate this objection to the use of lasting tacks, under one practice the shoes have been allowed to remain in lasted conditi n a considerable length of time until tl -e uppc has become set to the contour of the last. The lasting tacks are then withdrawn, and a lesser number of stay tacks are driven through the upper to hold it in position tcni- -porarily during the inseaming operation.

While this practice reduced. to some extent, the difficulty above referred toit failed to prevent an occasional breakage of the awl and needle oli the ins'eamin z machine as. while the stay tacks were less in number than the lasting tacks, they W01;- also driven perpendicular to the plane of the shoe bot tom, and hence lay directly in the path of the needle and awl'as they passed through the between substance in a. substantially horizontal direction.

The present method has for one of its principal objects the entire elimination of lasting tacks as a securing ineans for the successively stretched and overworked sections of upper in hand method lasting, whereby the objections to such tacks, or to any like fastenings for the upper sections that extend in the path of movement of the awl and needle, are obviated.

lVith such object in view this method includes the driving of independent fastenings through the upper sections and the lip of the innersole in a direction substantially parallel. with the last bottom as said sections are worked successively into lasted position. These fastcnings not only act transversely ofthe lip, but are located above the path usually traversed by the awl and needle, and hence oii'er no obstruction to the operation of said elements. While the method, in its broadest aspect, contemplates applying fastenings of any appropriate character trans- 'versely of the lip to secure the successively overworked upper sections thereto, it is preferred to use for this purpose staples of fine wire whose ends are clenched upon the inner side of the lip of the innersole. These particular fastenings otl'cr practically no obstruction to the owl and needle, but nevertheless may he made sufliciently strong to etlectivcly secure the upper under lasting tension to the lip of the innersole if inserted progressively as the lasting is perform'd step by step along the sides of the shoe {liikl to ho d the upper in such position until the completion of the inseamin z operation.

This method may .be practised by the hands of a shoemake with the aid of such simple tool as are well known to workers in this art. or it may be very eflectually practised by aid of machinery comprising upper stretching grippers of the hand method lasting machine type and staple fastening mechanism such, for example, as proposed by Drev in United States Letters Patent No. 1.011.592, which grippers and stapling mechanism have been organized into a machine, which described and claimed in pending application, Serial No. (323,860. filed April 23, 1911, for the purpose of practising my invention. I Other machines designed for use position by an independent fastening that is inserted through the upper andvlip in a direction'transverse to the lip, the overworking, forcing and securing being carried out successively relative to each other and progressively along first one side of the shoe and then along the other side.

JnWQJThat improvement in methods of maksition as it islasted by a staple through ing welt shoes which consists in lasting a shoe step by step by repeated operations applied progressively to successive portions of the shoe and fifs'fening each portion in position as it is lasted by a separate metallic fastening inserted in a 'direction substantially parallel with the shoe bottom through i the upper and through the lip of a; welt shoe innersole and clenched to secure it in upper fastening posltion. I

That improvement in methods of making welt shoes which consists in lasting a below the plane ofsaid fastenings and thereby tightening the lasted upper by drawing it into-the anglebetween the said lip and the feather of the innersole.

' 4:. A method for use in the manufacture of shoes, comprising working successive portions of an upper over a last by repeated operations, forcing each section of upper as it is overworked into the angle formed by the lip and feather edge of an inner-sole, driving each section of the upper while it is h'eldin said angle, and clenching the ends of the staple on the inside of the li 5. A'methodjz'or use in the manufacture verworked of shoes, comprising working successiye portions of an upper over a last by repeated operations, driving a staple through each over worked section of the upper and the" lip of an inner-sole in a directign transverse to the lip, and clenching the ends of each staple on the inside of the lip.

- (3. Ametliod foivuse in the manufacture of shoes, comprising working successive portions of an upper over a last by repeated opcrations and securing each portion of the upper as it is overworked to the lip'of an innersole by driving .as taple through the upper and lip in a direction transverse to the lip. v

. 7. A method for use'in the-manufacture of shoes, comprising working an upper over a last by repeated operations-, and'driving through each section of the upper as itis and through the lip of aninnersole a separate fastening which lies above the line in which the inseam stitcheslare to be inserted. f

8. A method for use in the manufacture of shoes, comprising pulling an upper to a last and laying it over upon an innersole provided with a lip by repeated operations,

and inserting a separate fastening througheach section of the upper as it is overworked and through'the lip in a direction substantially parallel with the shoe bottom.

9. A method for use in thenmanufacture of shoes, comprising working an upper by' repeated operations over a last having there-- lip, and inserting an individual fastening through each on an, innersole provided with a portion of the upper as it is overworked and through the lip transversely of the lip to secure the upper in position. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
